As vSphere evolves in functionality in terms of lifecycle management, even internally at Dell, I see confusion sometimes regarding the value of VxRail.
I started to hear about this since late 2018, when vSphere Update Manager (VUM) with vSphere 6.7 U1 started to also update drivers/firmware for the storage controllers for selected vendors, and now with vSphere 7.0 and the new vSphere Lifecycle Manager (vLCM) even the name makes things more confusing.
